Description

  The present invention relates to a technique for applying biometric authentication, particularly biometric authentication based on features associated with “hands” such as palm veins and fingerprints, to a gate system (passage authentication system) such as an entrance / exit management system or an automatic ticket gate at a station. .

  Biometric authentication is a technique for identifying an individual using biological characteristics (such as fingerprints and faces) and behavioral characteristics (such as voice and actions) of a person. In biometric authentication, the person's feature data is registered in advance as a template. At the time of authentication, the feature data acquired by the authentication sensor is compared with the registered template, and a degree of similarity representing how much both are similar is calculated. If the degree of similarity exceeds a certain value, the person is determined to be the person.

  In biometric authentication using a biometric image, biometric features are not input in exactly the same posture during registration and verification. For this reason, it is common to perform collation processing while aligning so as to allow a certain posture variation. For example, a comparison process with a registered template is performed while performing image conversion such as translation and rotation on the collation data, and the maximum similarity is searched. In many cases, the matching process is often terminated when the similarity exceeds a predetermined threshold. For this reason, if the posture variation during collation is large, extra time is required for the collation process. Further, if the posture fluctuation exceeds a certain range, it cannot be compensated by image conversion, and authentication accuracy is lowered.

  On the other hand, many biometrics use features (fingerprints, palm veins, etc.) associated with “hands”. This is because (1) the hand is exposed to the outside and (2) the high degree of freedom of movement is advantageous as biometric authentication. Specific biometric features include fingerprints, handprints, palm prints, veins, and the like. Accordingly, in the following, only biometric authentication using features associated with “hand” as biometric features will be considered as biometric authentication.

  In many cases, a biometric authentication device using a hand can be used with either the left or right hand. For example, left and right fingerprints are registered at the time of registration, and authentication is possible regardless of which fingerprint is used at the time of authentication. Specifically, the input fingerprint feature data and the registered left and right fingerprint templates are sequentially compared, and if any similarity exceeds a predetermined threshold, it is determined that the person is the person.

  However, since most biometric authentication devices are right-handed people, they are mostly designed with priority on the right hand. For example, in the case of an entrance / exit management device, the reading sensor is often arranged on the right side of the door.

  In the authentication sensor having such an arrangement, a left-handed person needs to authenticate using a hand that is not a dominant hand, and there is a problem that convenience is lowered. In addition, since it becomes difficult to accurately input the authentication feature to the authentication sensor, there is a problem that the authentication speed and authentication accuracy of biometric authentication are lowered. A similar problem occurs when a right-handed person wants to authenticate with his left hand when he has his right hand injured or has a heavy load. In particular, considering a case where biometric authentication is applied to authentication of a large number of people, such as a gate-type entrance / exit management system or a ticket gate at a station, it is essential that authentication can be performed smoothly. To that end, it is important that the user can authenticate in a natural manner whether right-handed or left-handed.

  Patent Documents 1 and 2 disclose documents related to biometric authentication using both the right hand and the left hand.

  FIG. 1 is a diagram showing an outline of the technique disclosed in Patent Document 1. In FIG. In FIG. 1, an automatic transaction apparatus 101 such as a bank ATM apparatus is often provided with a biometric authentication apparatus 103 on the right side of the display panel 102. In this case, although it is easy for the user 104 to operate with the right hand, it is difficult to use with the left hand, so the biometric authentication device 103 is configured to be rotatable so that it can be easily used with the finger of the left hand. . However, when using the left hand, it is necessary to extend the hand greatly, and it cannot be used in the same way as the right hand. In addition, it is necessary to provide a dedicated rotation mechanism, and there are significant demerits from the viewpoint of maintenance and cost.

  FIG. 2 is a diagram showing an outline of the technique disclosed in Patent Document 2. As shown in FIG. In FIG. 2, the traffic control device main body 203 is common to the two rooms 201 and 202. For example, when the fingerprint of the left hand is authenticated, the left room 201 can be entered by the electric lock control unit 204. When the fingerprint of the right hand is authenticated, the right room 202 can be entered by the electric lock control unit 205. Thereby, the installation cost in the case of managing the user's entry into a plurality of management sections is reduced, and the use efficiency of the space is improved.

  However, since the fingerprint reading surface is associated with the control of the management section, there is no effect of improving the convenience of the right / left hand user. For example, it is necessary to use a predetermined reading surface to enter a certain section, and there is no effect that the user's favorite reading surface can be used. As a result, the user is forced to use a hand that is not his / her dominant hand, so that convenience is reduced and authentication accuracy and authentication time are reduced as a result of the resulting posture fluctuation.

  Considering the use of biometric authentication in a wide range of application fields, it is desirable to be able to authenticate with the same ease of use with either the right hand or the left hand. In particular, when applying to authentication of a large number of people, such as a gate-type entrance / exit management system and a ticket gate at a station, authentication with both hands is essential to realize a smooth authentication service.

  If the user is forced to authenticate with an unfamiliar hand, the biometric feature cannot be successfully held over the authentication sensor, causing a psychological burden. Further, unlike a non-contact type IC card or the like, in the case of biometric authentication, it is necessary to cause the authentication sensor to accurately read the authentication feature surface, and thus more accurate control is required. Therefore, when the non-dominant hand is used for authentication, there is a problem that more posture changes are caused at the time of verification, leading to a decrease in authentication speed and authentication accuracy. Furthermore, it may be difficult to use the right hand for authentication because even right-handed people have luggage in the right hand or are injured and cannot use the right hand. In order to deal with such a case, it is desired that authentication can be performed with the left and right hands in the same manner.

  However, if two devices are simply prepared and used for the right hand and the left hand, the number of devices is twice as large, and there is a problem that it is very expensive. In particular, when a plurality of passages are provided for use by a large number of people, the installation cost of the apparatus becomes a big problem.

  In view of the above-described conventional problems, an object is to provide a traffic authentication system capable of performing authentication in the same way with left and right hands without increasing the cost of installing the apparatus.

In one embodiment of this traffic authentication system, each is provided with an authentication sensor that acquires biometric data from the presented hand, and is arranged separately from each other to form a plurality of passages. A plurality of gate management devices each provided with a gate that can be opened and closed except when arranged at either one of the left ends , an authentication verification result based on biometric data acquired from the authentication sensor, and the biometric data is either left or right Authentication means for outputting a left / right determination result as to whether the data is hand data, and a control means for controlling opening / closing of the corresponding gate based on the left / right determination result based on the authentication collation result, the control means, When the passage direction of the passage is one direction, the left and right passage management result of the gate management device on the left side is the right hand, left hand, or right hand. Controls the opening of the gate of the passage when the right / left determination result of the right gate management device is the right hand, and for the right end passage, the right / left determination result of the right gate management device is the right hand, left hand, or left side. When the left / right discrimination result of the gate management device is a left hand, control is performed to open the gate of the passage. For the other passages, the left / right discrimination result of the left gate management device is the left hand or the right gate management device. When the right / left discrimination result is right hand, control to open the gate of the passage is performed.

  In the disclosed traffic authentication system, the authentication sensor with the number of passages + 1 can suffice, so it is possible to perform authentication in the same way with the left and right hands without increasing the cost of installing the device, thereby improving convenience and authentication accuracy. be able to.

<Configuration>
FIG. 3 is a diagram illustrating a configuration example of a biometric gate system (passage authentication system) according to an embodiment.

  3, the biometric authentication gate system includes a system management terminal 1, a plurality of gate management devices 2 # 1 to 2 # 4, a plurality of gates 3 # 1 to 3 # 3, and a biometric authentication processing server 4. ing. The biometric authentication processing server 4 is used when centralized authentication processing (centralized authentication processing), and is used when distributed authentication processing (distributed authentication processing) is performed by the gate management devices 2 # 1 to 2 # 4. Not in.

  The system management terminal 1 is a part that performs overall management of the biometric authentication gate system, and is electrically connected to the biometric authentication processing server 4 and each of the gate management devices 2 # 1 to 2 # 4 to register / delete biometric data. Set the gate control table, open and close the gate.

  The gate management devices 2 # 1 to 2 # 4 are parts that acquire the biometric data of the user who is going to pass and open and close the gate according to the authentication result. The authentication result includes an authentication verification result indicating that the registered user is confirmed by the verification, and a direction determination result indicating whether the biometric data confirmed by the verification is left or right hand data. And a presentation direction discrimination result (angle information) indicating the direction of the presented hand with respect to the biometric data confirmed by the collation.

  Each of the gate management devices 2 # 1 to 2 # 4 is provided with authentication sensors 21 # 1 to 21 # 4 that acquire biometric data from a hand held by the user. The gate management devices 2 # 1 to 2 # 4 are provided at predetermined intervals between the impassable portions 6 and 7 such as walls and fences, and form a plurality of passages 5 # 1 to 5 # 3. The figure shows a state seen from above the passage. There are cases where the passage direction in which authentication is performed is one direction from the bottom to the top in the figure, and there are cases where the passage is a two-way direction including the top and bottom directions. In the case of managing only entrance to a specific facility, the direction of the passage for performing authentication can be one direction. When the direction of the passage for performing authentication is one direction, when the passage in the reverse direction is also used, the passage in the reverse direction can be freely performed. When it is necessary to manage entry and exit from a specific facility, the direction of the passage for authentication needs to be bidirectional. For example, when biometric authentication is applied to a ticket gate at a station, both information is necessary for billing, so entry and exit must be managed. When the path direction for authentication is configured to correspond to both directions, the configuration of the gate can be freely changed to entry-only / exit-only / both, enabling efficient system operation.

  The gates 3 # 1 to 3 # 3 are provided in the gate management devices 2 # 1 to 2 # 3, respectively, and the gate management device 2 # 4 has no gate. In addition, although it has shown about the case where the number of gate management apparatuses is four and three passages are shown, the number of paths can be increased or decreased by increasing or decreasing the number of gate management apparatuses. In this case, the number of gate management devices is a value obtained by adding 1 to the number of passages.

  The biometric authentication processing server 4 is a part that performs authentication processing intensively by comparing the biometric data acquired by the gate management devices 2 # 1 to 2 # 4 with a template of biometric data registered in advance. The system management terminal 1 and the gate management devices 2 # 1 to 2 # 4 are electrically connected.

  FIG. 4 is a diagram illustrating a configuration example of a biometric gate system in the case of centralized authentication processing, which is suitable for relatively small-scale operation.

  In FIG. 4, the system management terminal 1 includes a biometric data management unit 11, an all gate control table management unit 12, and an all gate monitoring unit 13.

  The biometric data management unit 11 is a part that manages the biometric data of the user, and registers biometric data including a template indicating the biometric feature of the user in a master database 43 described later of the biometric authentication processing server 4.

  The all gate control table management unit 12 is a part that manages a gate control table 23 to be described later of all the gate management devices 2 # 1 to 2 # 4. On the other hand, the gate control table 23 is set. Further, the contents of the gate control table are returned in response to the reference from all the gate monitoring units 13.

  The all gate monitoring unit 13 monitors the operating state of all the gate management devices 2 # 1 to 2 # 4, and sends an instruction to open the gate (gate opening instruction) to the corresponding gate management device if necessary. The all gate monitoring unit 13 receives the authentication result and the gate number to be opened from all the gate management devices 2 # 1 to 2 # 4, and when the gate to be opened is a gate of another gate management device, the gate management device 13 Send open instructions. Further, when dynamically assigning temporary authentication priority or the like, the all gate monitoring unit 13 refers to the contents of the gate control table from the all gate control table management unit 12, and the gate control table 23 of the corresponding gate management device. Set to.

  Each of the gate management devices 2 # 1 to 2 # 4 includes an authentication sensor 21, a biometric authentication unit 22, a gate control table 23, a gate control unit 24, and a gate opening / closing device 25.

  The authentication sensor 21 is a sensor that reads a biometric feature that performs biometric authentication. More specifically, a reading sensor such as a fingerprint, a palm vein, or a palm shape is applicable. The authentication sensor 21 also includes a distance sensor, a touch sensor, and the like that detect that the user's hand has been presented in order to obtain the timing for starting the reading operation.

  The biometric authentication unit 22 is a part that mediates biometric authentication by the biometric authentication processing server 4. That is, biometric data is received from the authentication sensor 21 and an authentication request is sent to the biometric authentication processing server 4. At that time, the biometric authentication unit 22 refers to the gate control table 23 and sends an authentication condition list including a plurality of authentication conditions, which are conditions for executing the biometric authentication process, to the biometric authentication processing server 4 together with the biometric data. The authentication condition is information including which of the left and right sides of the template is to be authenticated, or authentication priority, temporary authentication priority, etc., which will be described later. When the left and right hands are authenticated equally, the authentication condition list includes the authentication condition “authentication target template L / R flag: L” and the authentication condition “authentication target template L / R flag: R”. In addition, when authenticating the left and right hands equally, an implementation may be made such that an authentication condition list is not added. The biometric authentication unit 22 sends the authentication result received from the biometric authentication processing server 4 to the gate control unit 24. The authentication result indicates that the value of the L / R flag (“L” or “R”) of the template is provided on the condition that the biometric data acquired from the user matches one of the registered templates (similarity by collation is a predetermined value or more). )It is included. Further, in the case of a bidirectional passage, a collation angle (relative rotation angle of the image when the coincidence between the biometric data and the registered template is confirmed) Δθ is further included.

  The gate control table 23 is a data structure describing the correspondence between the authentication result and the gate to be opened. Since the gate management devices 2 # 1 to 2 # 4 divide the plurality of passages 5 # 1 to 5 # 3, the positions where the user can exist are limited to several patterns, and the user can move either the right hand or the left hand. Since it is presented, the position of the user can be estimated from the authentication result, and the gate opening / closing can be appropriately controlled. A specific example of the gate control table 23 will be described later.

  The gate control unit 24 is a part that performs control to open the gate 3 (3 # 1 to 3 # 3) by the gate opening / closing device 25 based on the authentication result. The gate to be opened is identified from the authentication result with reference to the gate control table 23, and when it is the gate of the own device, the gate is opened autonomously. Also, the authentication result and the gate number of the gate to be opened are notified to all the gate monitoring units 13 of the system management terminal 1, and when the gate open instruction is given from all the gate monitoring units 13, the gate of the own device is opened.

  The gate opening / closing device 25 is a device that physically opens and closes the gate 3 (3 # 1 to 3 # 3) of its own device in accordance with an instruction from the gate control unit 24. In addition, since the gate does not exist in the terminal gate management device 2 # 4, the gate opening / closing device 25 is unnecessary.

  The biometric authentication processing server 4 includes a biometric authentication control unit 41, a biometric authentication engine 42, and a master database 43.

  The biometric authentication control unit 41 is a part that processes authentication requests from the gate management devices 2 # 1 to 2 # 4. When the biometric authentication control unit 41 receives the authentication condition list from the biometric authentication unit 22 of the gate management apparatus 2 together with the biometric data to be authenticated, the biometric authentication control unit 41 sends the biometric data and the authentication condition to the biometric authentication engine 42 and receives the authentication result. And returned to the biometric authentication unit 22 of the gate management device 2.

  The biometric authentication engine 42 is a part that executes an authentication process by matching biometric data with a registered template. That is, when the biometric authentication engine 42 receives the biometric data and the authentication conditions as necessary from the biometric authentication control unit 41, the biometric authentication engine 42 compares all the registered templates with the acquired biometric data with reference to the master database 43 and calculates the similarity. If the calculated maximum similarity exceeds a predetermined threshold, the user ID corresponding to the registered template, the L / R flag of the template, and the verification angle Δθ as necessary are output as an authentication result. To do. Even if the comparison with all registered templates is not completed, if the degree of similarity exceeds a predetermined threshold, the authentication result may be output at that time.

  The master database 43 is a part for storing user biometric data. A data example will be described later.

  FIG. 5 is a diagram showing a configuration example of a biometric authentication gate system in the case of distributed authentication processing, and is suitable for large-scale operation. In FIG. 5, the biometric authentication control unit 41, the biometric authentication engine 42, and the master database 43 that are components of the biometric authentication processing server 4 in FIG. 4 are gated as the biometric authentication control unit 26, the biometric authentication engine 27, and the local memory 28. It is built in the management apparatus 2 (2 # 1-2 # 4). Since the biometric authentication engine 27 only needs to perform the authentication process on the biometric data acquired by the own device using the local memory 28, the authentication process can be performed at high speed.

  FIG. 6 is a diagram showing an example of registered biometric data stored in the master database 43 (FIG. 4) of the biometric authentication processing server 4 or the local memory 28 (FIG. 5) of the gate management device 2 (2 # 1-2 # 4). It is.

  The registered biometric data includes items of “user ID”, “L / R flag”, and “registered template”. The user ID is a unique identification symbol assigned to registered users on a one-to-one basis. The L / R flag is a flag indicating whether the corresponding registration template is a left-handed one or a right-handed one. The registered template is biometric feature data itself used for biometric verification processing, for example, fingerprint feature data extracted from a fingerprint.

  FIG. 7 is a diagram showing an example of the gate control table 23 in the case of a one-way passage. As shown in FIG. 3, three gates 5 # 1 to 5 # 1 are arranged by four gate management devices 2 # 1 to 2 # 4. The example of the gate control table 23 of each gate management apparatus 2 # 1-2 # 4 in case 5 # 3 is formed is shown. The gate control table 23 stores the value of the “template L / R flag”, which is the authentication result, and the “open gate” in association with each other.

  In the gate control table 23 of the gate management apparatus 2 # 1 shown in FIG. 7A, "L" and "R" of the "template L / R flag" as the authentication result are "gate # 1". (Gate 3 # 1). This is because, as shown in FIG. 8A, the user U presented the left hand to the authentication sensor 21 # 1 of the gate management device 2 # 1, and therefore the “L / R flag of the template” is “L”. Even when the determination is made, it is determined that the L / R flag of the template is “R” because the user U unnaturally presented the right hand to the authentication sensor 21 # 1 as shown in FIG. 8B. Even in this case, the “open gate” is gate 3 # 1.

  In the gate control table 23 of the gate management device 2 # 2 shown in FIG. 7B, when the “template L / R flag” is “L”, the “open gate” is “gate # 2” (gate 3 # 2). ) When the “template L / R flag” is “R”, the “open gate” is “gate # 1” (gate 3 # 1). This is because, as shown in FIG. 8C, the user U presented the left hand to the authentication sensor 21 # 2 of the gate management device 2 # 2, and thus the “template L / R flag” is “L”. If so, the “gate to open” is gate 3 # 2. Further, as shown in FIG. 8D, the user U presents the right hand to the authentication sensor 21 # 2 of the gate management apparatus 2 # 2, so that the “template L / R flag” is determined to be “R”. If so, the “gate to open” is gate 3 # 1.

  In the gate control table 23 of the gate management device 2 # 3 shown in FIG. 7C, when the “template L / R flag” is “L”, the “open gate” is “gate # 3” (gate 3 # 3). ) When the “template L / R flag” is “R”, the “open gate” is “gate # 2” (gate 3 # 2). This is for the same reason as in the case of the gate management device 2 # 2.

  In the gate control table 23 of the gate management device 2 # 4 shown in FIG. 7D, “L” and “R” of the “template L / R flag” as the authentication result are “gate # 3”. (Gate 3 # 3). This is for the same reason as in the case of the gate management apparatus 2 # 1.

  FIG. 9 is a diagram showing an example of the gate control table 23 in the case of a bidirectional passage. As shown in FIG. 3, three gates 5 # 1 to 5 # 1 are provided by four gate management devices 2 # 1 to 2 # 4. The example of the gate control table 23 of each gate management apparatus 2 # 1-2 # 4 in case 5 # 3 is formed is shown. The gate control table 23 stores “open gate” in association with the value of the “template L / R flag” and the value of “collation angle Δθ”, which are authentication results.

  FIG. 10 is a diagram illustrating an example of a correspondence relationship between the collation angle Δθ and the user's intrusion direction, and illustrates an example in which a fingerprint is used as a biometric feature.

  FIG. 10A shows a case where the user progresses upward in the figure, in a state where the registration template T is rotated about 40 ° as the collation angle Δθ with respect to the collation data D acquired from the user. A match is confirmed. Even when both the right hand and the left hand are considered, it can be determined that the traveling direction is upward when the collation angle Δθ is in the range of −90 ° to + 90 °.

  FIG. 10B shows a case where the user progresses downward in the figure, in a state where the registration template T is rotated about 140 ° as the collation angle Δθ with respect to the collation data D acquired from the user. A match is confirmed. Even when both the right hand and the left hand are considered, it can be determined that the traveling direction is downward when the collation angle Δθ is out of the range of −90 ° to + 90 °.

  Returning to FIG. 9, the gate control table 23 of the gate management device 2 # 1 shown in FIG. 9A stores “L” “R” and “collation angle Δθ” of the “template L / R flag” as the authentication result. Regardless, the “open gate” is “gate # 1” (gate 3 # 1). This is because, when authenticated by the authentication sensor 21 # 1 of the gate management device 2 # 1, only the gate 3 # 1 can be selected as the “open gate” regardless of the right hand / left hand and the traveling direction.

  In the gate control table 23 of the gate management apparatus 2 # 2 shown in FIG. 9B, the “template L / R flag” is “L” and the “verification angle Δθ” is “−90 ° ≦ Δθ ≦ + 90 °”. If the “open gate” is “gate # 2” (gate 3 # 2), the “template L / R flag” is “L”, and the “verification angle Δθ” is “other than the above”, the “open gate” is "Gate # 1" (gate 3 # 1). This is because when the “template L / R flag” is determined to be “L” and the “collation angle Δθ” is determined to be “−90 ° ≦ Δθ ≦ + 90 °”, FIG. This is because the “open gate” is the gate 3 # 2. When it is determined that the “template L / R flag” is “L” and the “collation angle Δθ” is determined to be “other than the above”, the state shown in FIG. Yes, the “gate to open” is gate 3 # 1.

  Further, in the gate control table 23 of the gate management device 2 # 2 shown in FIG. 9B, the “template L / R flag” is “R” and the “collation angle Δθ” is “−90 ° ≦ Δθ ≦ + 90 °. "Open gate" is "Gate # 1" (Gate 3 # 1), "Template L / R flag" is "R" and "Verification angle Δθ" is "Other than above", "Open gate" “Gate # 2” (gate 3 # 2). This is because when the “template L / R flag” is determined to be “R” and the “collation angle Δθ” is determined to be “−90 ° ≦ Δθ ≦ + 90 °”, FIG. This is because the “open gate” is the gate 3 # 1. Further, when it is determined that the “template L / R flag” is “R” and the “collation angle Δθ” is determined to be “other than the above”, the state shown in FIG. Yes, because the “open gate” is gate 3 # 2.

  In the gate control table 23 of the gate management apparatus 2 # 3 shown in FIG. 9C, the “template L / R flag” is “L” and the “verification angle Δθ” is “−90 ° ≦ Δθ ≦ + 90 °”. In this case, “open gate” is “gate # 3” (gate 3 # 3), “template L / R flag” is “L”, and “verification angle Δθ” is “other than the above”, “open gate” is “Gate # 2” (Gate 3 # 2). Further, when the “template L / R flag” is “R” and the “verification angle Δθ” is “−90 ° ≦ Δθ ≦ + 90 °”, the “open gate” is “gate # 2” (gate 3 # 2). When the “template L / R flag” is “R” and the “collation angle Δθ” is “other than the above”, the “open gate” is “gate # 3” (gate 3 # 3). This is for the same reason as in the case of the gate management device 2 # 2.

  The gate control table 23 of the gate management device 2 # 4 shown in FIG. 9D has “L”, “R”, and “collation angle Δθ” of the “template L / R flag” that is the authentication result. The gate to be opened is “Gate # 3” (Gate 3 # 3). This is for the same reason as in the case of the gate management apparatus 2 # 1.

<Operation>
FIG. 12 is a flowchart showing an example of processing according to the above-described embodiment. FIG. 12A is a biometric data registration process, FIG. 12B is a gate control table setting process, and FIG. The process of gate control is shown.

  In FIG. 12A, when the system administrator starts the process in a timely manner (step S11), the biometric data management unit 11 of the system management terminal 1 to the master database 43 (FIG. 4) of the biometric authentication processing server 4 or the gate management device. Biological data is registered in the local memory 28 (FIG. 5) of 2 (2 # 1 to 2 # 4) (step S12), and the process is terminated (step S13). The registered biometric data is as shown in FIG.

  In FIG.12 (b), if a process is started with starting of a biometrics gate system (step S21), all the gate control table management parts 12 of the system management terminal 1 will be the gate management apparatus 2 (2 # 1-2 #). The table contents are set for each apparatus in the gate control table 23 of 4) (step S22), and the process is terminated (step S23). The contents of the set gate control table 23 are as shown in FIG. 7 in the case of a one-way passage and in FIG. 9 in the case of a bidirectional passage, and differ depending on the device.

  In FIG. 12C, each gate management device 2 (2 # 1 to 2 # 4) detects the presentation of the user's hand with a distance sensor, a touch sensor, or the like provided in the authentication sensor 21, and starts processing. In step S101, the biometric authentication unit 22 acquires biometric data by the authentication sensor 21 (step S102). That is, the biometric authentication unit 22 detects the start of authentication while communicating with the authentication sensor 21, and when detecting the user's hand, instructs the authentication sensor 21 to acquire biometric data and acquires biometric data.

  Next, the biometric authentication unit 22 makes an authentication request to the biometric authentication control unit 41 (FIG. 4) or the biometric authentication control unit 26 (FIG. 5) of the biometric authentication processing server 4 (step S103).

  Upon receiving the authentication request, the biometric authentication control unit 41 (FIG. 4) or the biometric authentication control unit 26 (FIG. 5) performs an authentication process (step S104). Details of the authentication process will be described later.

  Next, the biometric authentication control unit 41 (FIG. 4) or the biometric authentication control unit 26 (FIG. 5) returns an authentication result to the biometric authentication unit 22 (step S105).

  The biometric authentication unit 22 that has obtained the authentication result notifies the gate control unit 24 of the authentication result (step S106).

  The gate control unit 24 that has obtained the authentication result refers to the gate control table 23 and specifies a gate to be opened according to the authentication result (step S107). That is, in the case of a one-way passage, the gate control table 23 of FIG. 7 is referred to, and the “gate to be opened” is specified from the “template L / R flag” of the authentication result. In the case of a bidirectional path, the gate control table 23 in FIG. 9 is referred to, and the “gate to be opened” is identified from the “template L / R flag” and the “verification angle Δθ” of the authentication result.

  Returning to FIG. 12C, the gate control unit 24 notifies all gate monitoring units 13 of the system management terminal 1 of the authentication result and the gate number of the identified “gate to be opened” (step S <b> 108).

  Next, the gate control unit 24 determines whether or not the identified “open gate” is the gate 3 managed by the own device (step S109). If the gate 3 is managed by the own device (Yes in step S109), the gate opening / closing device 25 is instructed to open the gate, and the gate opening / closing device 25 opens the gate 3 for a predetermined time by an internal timer and then closes it. Is performed (step S110), and the process is terminated (step S113).

  If it is not the gate 3 managed by the own device (No in step S109), the all gate monitoring unit 13 of the system management terminal 1 issues a gate open instruction to the gate control unit 24 of the corresponding gate management device 2 (step S111).

  The gate control unit 24 of the gate management device 2 that has received the gate open instruction issues a gate open instruction to the gate opening / closing device 25 of its own device, and the gate opening / closing device 25 performs an operation of opening the gate 3 for a predetermined time and then closing it (step). In step S112, the process ends (step S113).

  FIG. 13 is a flowchart illustrating an example of authentication processing.

  In FIG. 13, when processing is started (step S201), initialization processing is performed (step S202). The initialization process includes the template number i to be collated, the maximum similarity Smax, the IDmax of the template that gives the maximum similarity, the L / Rmax that is the L / R flag of the template that gives the maximum similarity, and the maximum similarity Are set to “0”, respectively. In the case of a one-way passage, Δθmax is not necessary.

  Next, it is determined whether or not collation with all data has been completed based on whether or not the number i has reached the total number N of registered templates (step S203). If it is determined that collation with all data has been completed (YES in step S203), the process ends (step S208).

  If it is determined that collation with all data has not been completed (NO in step S203), the maximum value Si of the similarity is calculated for the i-th template while changing the collation angle Δθ, and the ID of the i-th template is calculated. Is IDi, the L / R flag of the i-th template is L / Ri, and the collation angle Δθ that gives the maximum value Si is Δθi (step S204). In the case of a one-way passage, Δθi is not necessary.

  Next, it is determined whether or not Si exceeds Smax (step S205). If it exceeds (YES in step S205), the maximum similarity or the like is updated (step S206). That is, Si is set to Smax, IDi is set to IDmax, L / Ri is set to L / Rmax, and Δθi is set to Δθmax. In the case of a one-way passage, Δθmax is not necessary.

  Next, “1” is added to the number i (step S207), and the process returns to the determination (step S203) as to whether or not collation with all data has been completed.

  If the maximum similarity Smax exceeds a predetermined value after the end of the process (step S208), IDmax, L / Rmax, and Δθmax are authentication results.

<Example with special authentication conditions>
First, when the characteristic (how to be used) for each passage is known in advance, the authentication process can be efficiently performed by using the characteristic. For example, when there are a plurality of passages as shown in FIG. 3 and the one-way passage is upward from the bottom of the figure, the leftmost gate management device 2 # 1 as viewed from the user is actually mostly left-handed. Expected to be used. It is expected that many left-handed people will gather because of the use of the left hand. Therefore, the authentication process can be made efficient by dedicating the corresponding gate management device 2 # 1 to the left hand and limiting the authentication target template to the left hand.

  FIG. 14 is a diagram showing an example of the gate control table 23 and the authentication condition list when limiting the authentication target. The gate management device 2 # 1 in FIG. 4 or 5 is dedicated to the left hand, and the passage 5 # 1 is viewed from below. It is an example in the case of authenticating only in one direction upward.

  FIG. 14A shows an example of the gate control table 23 of the gate management apparatus 2 # 1, in which only “L” is set in the “template L / R flag” and the corresponding “open gate” is set to “gate”. # 1 "(gate 3 # 1).

  FIG. 14B shows the authentication from the biometric authentication unit 22 of the gate management device 2 # 1 to the biometric authentication control unit 41 (FIG. 4) or the biometric authentication control unit 26 (FIG. 5) of the biometric authentication processing server 4 during the authentication process. An example of an authentication condition list to be sent in a request is shown, and only an authentication condition of “authentication target template L / R flag: L” indicating that the authentication target is the left hand is set.

  In this case, the biometric authentication engine 42 (FIG. 4) or the biometric authentication engine 27 (FIG. 5) of the biometric authentication processing server 4 sets only the template whose “L / R flag” is “L” according to the authentication condition as an authentication target. Since the template with the “L / R flag” of “R” can be skipped, the resources (processing time and calculation power) required for the authentication processing are reduced to about half.

  On the other hand, when the left-handed gate management device is provided as described above, it can be expected that many left-handed people gather in the adjacent gate management devices. This occurs because left-handed people concentrate on the left-handed gate management device, resulting in an overused person using a neighboring gate management device.

  In such a case, the authentication process can be made more efficient by providing “authentication priority” in the gate control table. Here, the authentication priority is a numerical value representing the priority of the authentication process, and the larger the value, the higher the corresponding authentication process priority.

  FIG. 15 is a diagram showing an example of the gate control table 23 and the authentication condition list when the authentication priority is given to the authentication target, and is an example applied to the gate management apparatus 2 # 2.

  FIG. 15A shows an example of the gate control table 23 of the gate management device 2 # 2, in which an item “authentication priority” is added to the content of FIG. "Authentication priority" when "is" L "is" 1 ", and" Authentication priority "is" 0 "when" L / R flag of template "is" R ". doing.

  FIG. 15B shows an authentication request from the biometric authentication unit 22 of the gate management device 2 # 2 to the biometric authentication control unit 41 (FIG. 4) or the biometric authentication control unit 26 (FIG. 5) of the biometric authentication processing server 4 during the authentication process. An example of an authentication condition list to be sent together is shown, and “authentication target template L / R flag: L authentication priority: 1” and “authentication target template L / R flag: R authentication priority: 0” are authentication conditions. Is set.

  In this case, the biometric authentication control unit 41 (FIG. 4) or the biometric authentication control unit 26 (FIG. 5) of the biometric authentication processing server 4 first requests the biometric authentication engines 42 and 27 to authenticate “L” of the template. . If the authentication is OK, the process is terminated at that time and the authentication result is returned. On the other hand, in the case of authentication NG, authentication processing is executed for “R” of the template. By preferentially executing an authentication process with a high probability, the authentication process can be performed efficiently.

  Second, when prediction based on the tendency of other gates can be performed, the authentication processing can be efficiently performed by changing the authentication priority according to the usage status of the other gates. For example, when considering use at a ticket gate at a station, it is expected that the use in the direction of exiting from the ticket gate will increase when a train arrives. Therefore, when authentication processing is executed at a certain gate, it is assumed that usage in the same direction will also increase at neighboring gates, and the authentication processing efficiency will be improved by temporarily setting the authentication priority. Can do. Here, it is assumed that it is a bidirectional passage.

  FIG. 16 is a diagram showing an example of the gate control table 23 and the authentication condition list when temporary authentication priority is given to the authentication target. When a person who uses the gate in the upward direction in FIG. In addition, this is an example of increasing the priority in the same direction. The above-mentioned “authentication priority” is a priority that is fixedly set according to the gate configuration, but the “temporary authentication priority” here is a value that is temporarily set according to the usage status of the gate. is there.

  FIG. 16A shows an example of the gate control table 23 of the gate management device 2 # 2, and an item “temporary authentication priority” is added to the content of FIG. When “Flag” is “L” and “Verification angle Δθ” is “−90 ° ≦ Δθ ≦ + 90 °”, “Temporary authentication priority” is “2”, and “Verification angle Δθ” is “Other than the above” “Temporary authentication priority” is “0”, “Template L / R flag” is “R”, and “Verification angle Δθ” is “−90 ° ≦ Δθ ≦ + 90 °”. The “temporary authentication priority” when “3” and “verification angle Δθ” are “other than the above” is “1”. In this case, the “temporary authentication priority” corresponding to Δθ in the same direction, that is, the same range is set to a high value. Also, since it is generally assumed that there are many users with the right hand, the “temporary authentication priority” of the right hand is set higher than that of the left hand. Therefore, here, the temporary authentication priority is set in four stages. The “temporary authentication priority” is set in the gate control table 23 of the gate management device 2 # 2 by all the gate monitoring units 13 of the system management terminal 1.

  FIG. 16B shows an authentication request from the biometric authentication unit 22 of the gate management apparatus 2 # 2 to the biometric authentication control unit 41 (FIG. 4) or the biometric authentication control unit 26 (FIG. 5) of the biometric authentication processing server 4 during the authentication process. An example of an authentication condition list to be sent together is shown. “Authentication target template L / R flag: L Δθ: −90 ° ≦ Δθ ≦ + 90 ° Temporary authentication priority: 2” and “Authentication target template L / R flag: L Δθ: Other than the above Temporary authentication priority: 0 ”and“ Authentication target template L / R flag: R Δθ: −90 ° ≦ Δθ ≦ + 90 ° Temporary authentication priority: 3 ”and“ Authentication target template L / R flag: R Δθ: Other than above Temporary authentication priority: 1 ”is set as the authentication condition.

  In this case, the biometric authentication control unit 41 (FIG. 4) or the biometric authentication control unit 26 (FIG. 5) of the biometric authentication processing server 4 performs authentication processing in descending order of priority, and gates the result when authentication is OK. Return to management device 2 # 2.

  Since “temporary authentication priority” is a temporary setting, it is valid only for a certain period of time, and after a certain period of time has elapsed, the corresponding part is cleared to zero. This zero clear may be performed by the gate monitoring unit 13 of the system management terminal 1 on the gate control table 23 of the gate management device 2 # 2, or a time stamp is added to the “temporary authentication priority”. You may perform autonomously by the gate management apparatus 2 # 2 side.

  Also, a configuration having both fixed “authentication priority” and “temporary authentication priority” may be adopted. In this case, the authentication process can be efficiently performed by performing both the fixed priority process according to the gate arrangement and the temporary priority process.

  Third, prediction based on the tendency of the previous person in the same gate management apparatus can be used. That is, when paying attention to a certain passage, it is expected that the traveling direction of the user is frequently changed, and the use in the same direction is expected to continue. This is because it can be expected that the gate is often used following the previous person.

  In order to improve processing efficiency in such a case, the authentication priority is temporarily increased in the gate management apparatus. That is, the temporary authentication priority for the authentication under the same condition as the authentication condition in the immediately preceding authentication process is increased.

  In addition, the authentication priority can be set according to time (setting of authentication priority according to time). For example, when used as a ticket gate of a station, the authentication process can be made more efficient by increasing the priority of the corresponding direction (direction to exit the ticket gate) at the train arrival time known in advance.

  In addition, when registering a biometric authentication registration template, a user's main hand is registered in advance, and authentication priority is set using the information (setting of authentication processing priority based on registration data). You can also In general, it is said that the ratio of right-handed users and left-handed users is constant, but when there are a relatively small number of registered users, the distribution of right-handed and left-handed users may be biased. In such a case, for example, when there are more registered users who mainly use the right hand than usual, the authentication processing can be made more efficient by setting the authentication priority accordingly.

(1) Since the authentication sensor with the number of passages + 1 is sufficient, the cost for installing the apparatus is not increased.
